From 51ceeedf8d6076eca1e7609c28a8788ede72ee5c Mon Sep 17 00:00:00 2001 From: Ancelin SERRE Date: Thu, 22 Oct 2026 21:23:32 +0200 Subject: [PATCH 1/2] feat: refine every lane's change in a second session, one tier up A lane went straight from delivery-implement to a draft pull request, so the human at the merge gate was the first to review the change and nothing simplified it. A sixth skill, delivery-refine, now runs as the lane's second session: it reviews the change against the task's acceptance criteria, fixes the findings that name a concrete failure, simplifies only the lines the change added without altering behaviour, re-runs validation, and adds a Refinement section to the report that becomes the pull request body. It runs one tier up (chore as build, build as plan, plan as plan), on that tier's harness and model, or on a tier's own reviewer key in tiers.conf, because a reviewer no stronger than the author finds little the author would not. A failed refinement never loses the implementation: the change is published as delivery-implement left it, and the report says so. --no-refine skips it. The session is started by the launcher through harness.sh, so it works on every adapter rather than relying on one harness's subagents. LAUNCHED and WOULD-LAUNCH gain the review harness and model after the lane's model. See ADR-011.

Fixing before simplifying keeps simplification from +polishing code that is about to change, and lets it tidy the fixes too. + +### 1. Review + +Read the change as a reviewer who did not write it. A finding names a concrete +failure: the input or state that triggers it, and what goes wrong. "This could +be clearer" is not a finding; it belongs to step 3, or nowhere. + +Look for: + +- **Criteria.** Each acceptance criterion: is it met by the change, and shown + by something that was actually run? +- **Edge cases.** Empty, missing, duplicated, out of order, concurrent, or at a + boundary: what input does the change handle wrongly? +- **Verification gap.** If this behaviour broke, would any test fail? +- **Unattended drift.** Changes outside the task's scope, validation reported + but not run, a test weakened or deleted to make validation pass. + +### 2. Fix + +Fix every finding inside the task's scope, smallest change first. A +verification gap is fixed by a test that would fail if the behaviour broke. + +A finding whose fix leaves the scope goes to the report as deferred, with its +failure stated. A finding that shows the task itself is wrong is reported as +open, prominently; do not revert the implementation, and do not rewrite the +task's approach. A human decides on the draft pull request. + +### 3. Simplify + +Make the change easier to read and to maintain, with exactly the same +behaviour: same outputs, errors, side effects and ordering. Only the lines this +change added or modified are in scope; code it merely sits next to is not, and +a wider refactor that would help goes to the report as deferred. + +Worth doing: + +- reuse a helper, pattern or module the repository already has instead of the + new code that duplicates it +- remove duplication within the change, dead code, unused parameters and + imports it introduced +- remove an abstraction, wrapper or indirection with a single caller and no + reason to exist yet +- flatten deep nesting with early returns; replace nested conditional + expressions with plain conditionals +- rename what the name misdescribes; match the naming, error handling and + structure of the neighbouring code +- delete comments that restate the code; keep the ones that say why + +Not worth doing, and to be undone if done: + +- fewer lines at the cost of clarity: dense one-liners, clever expressions +- merging unrelated logic, or removing an abstraction the codebase uses on + purpose +- removing or weakening error handling, validation or a safety check +- changing a test's assertions to fit a simplification: a simplification that + needs that changed behaviour + +The test for each simplification: would someone new to the code understand the +result faster than the original? When unsure, leave it. + +### 4. Validate + +Re-run the validation the report says `delivery-implement` ran, with the +repository's own commands, plus any test step 2 added. A simplification that +breaks validation is reverted, not the test. A fix that cannot be made to pass +is reverted and reported as open. + +Never weaken or delete a test to make validation pass. + +### 5.

A custom tier-above is now only chosen when DELIVERY_LANE_CMD is set. Adds tests for both, for the fallback to the lane's harness, and for where.sh reporting a missing delivery-refine.
